CVE-2024-55104 identifies multiple SQL injection vulnerabilities in the Online Nurse Hiring System v1.0, specifically within the /admin/add-nurse.php endpoint. The injection points are the 'gender' and 'emailid' parameters, which are improperly sanitized, allowing an attacker with administrative privileges to inject malicious SQL code. This vulnerability is classified under CWE-89, indicating classic SQL injection flaws. The CVSS v3.1 score of 7.2 reflects a high severity due to network attack vector (AV:N), low attack complexity (AC:L), but requiring high privileges (PR:H) and no user interaction (UI:N). The impact includes full compromise of confidentiality, integrity, and availability (C:H/I:H/A:H) of the backend database, enabling data exfiltration, unauthorized data modification, or deletion. Although no public exploits are currently known, the vulnerability's presence in a healthcare-related system poses a critical risk given the sensitivity of personnel and patient data involved. The lack of available patches necessitates immediate attention to secure coding practices and alternative mitigations.

The exploitation of this SQL injection vulnerability can lead to severe consequences for organizations using the Online Nurse Hiring System. Attackers with administrative access can execute arbitrary SQL commands, potentially extracting sensitive personal data of nurses and patients, modifying or deleting records, and disrupting system availability. This could result in data breaches violating privacy regulations such as HIPAA, reputational damage, and operational downtime affecting healthcare staffing processes. Given the critical nature of healthcare data and the reliance on accurate personnel information, the impact extends beyond IT systems to patient care quality and compliance obligations. Organizations worldwide that use this system or similar platforms are at risk of targeted attacks aiming to disrupt healthcare operations or steal sensitive information.

To mitigate CVE-2024-55104, organizations should immediately review and restrict administrative access to the Online Nurse Hiring System to trusted personnel only. Implement strong input validation and sanitization on all user-supplied parameters, especially 'gender' and 'emailid'. Employ parameterized queries or prepared statements to prevent SQL injection. Conduct a thorough code audit of the /admin/add-nurse.php component and related modules to identify and remediate similar vulnerabilities. If vendor patches become available, apply them promptly. Additionally, monitor database and application logs for suspicious queries or access patterns indicative of exploitation attempts. Consider deploying Web Application Firewalls (WAFs) with SQL injection detection rules tailored to this system. Regularly back up databases and test restoration procedures to minimize impact from potential data corruption or deletion.
